  Synthesis of 2‘-C-α-(Hydroxyalkyl) and 2‘-C-α-Alkylcytidine Phosphoramidites:  Analogues for Probing Solvent Interactions with RNA

  摘要：

  Nucleoside analogues bearing 2'-C-alpha-(hydroxyalkyl) and 2'-C-alpha-alkyl substitutes have numerous applications in RNA chemistry and biology. In particular, they provide a strategy to probe the interaction between the 2'-hydroxyl group of RNA and water. To incorporate these nucleoside analogues into oligonucleotides for studies of the group II intron (Gordon, P. M.; Fong, R.; Deb, S.; Li, N.-S.; Schwans, J. P.; Ye, J.-D.; Piccirilli, J. A. Chem. Biol. 2004, 11, 237), we synthesized six new phosphoramidite derivatives of 2'-deoxy-2'-C-alpha-(hydroxyalkyl)cytidine (36: R = -(CH2)(2)OH; 38: R = -(CH2)(3)OH; 40: R = -(CH2)(4)OH) and 2'-deoxy-2'-C-alpha-alkylcytidine (37: R = -CH2CH3; 39: R = -(CH2)(2)CH3; 41: R = -(CH2)(3)CH3) from cytidine or uridine via 2'-C-alpha-allylation, followed by alkene and alcohol transformations. Phosphoramidites 36 and 37 were prepared from cytidine in overall yields of 14% (10 steps) and 7% (11 steps), respectively. Phosphoramidites 38 and 39 were prepared from uridine in overall yields of 30% (10 steps) and 13% (11 steps), respectively. Phosphoramidites 40 and 41 were synthesized from uridine in overall yields of 21% (13 steps) and 25% (14 steps), respectively.
